Event - Definition of an event

Definition

Events and phases are concepts that apply to time.

• An event is a moment in time;
• A phase is a duration in time (delimited by two events; a start event and an end event).

An activity can have any number of events (zero or more), such as:

• FCE: moment of maximum or minimum angle (calculated according to defined suggestion);
• FCE: all local maxima and all local minima for that angle (as above);
• Shotput: moment of release;
• Tennis: moment of impact;
• Gait: left heel strike, left toe off, right heel strike, right toe off, etc.;
• Golf putting: ball address (BA), back swing (BS), through swing (TS), ball impact (BI), follow-through (FT);
• Any other event you care to define for any activity.
  

Any type of activity has its own specific events of interest. Such events are specified in the templates and in the database. New events can be added by the user.

APAS/Wizard makes a distinction between the following types of events:

• Automatic events are generated by APAS/Wizard based on existing clues as defined in the templates. Automatic events cannot be deleted or edited by the user. An automatic event will be shown in Quick Chart and Chart as a cross marking the value of the suggestion at that particular time. Automatic event detection has been enabled on all FCE analyses.
• Manual events can be added manually by the user as he sees fit.

Events show up in various places such as:

• Simple chart -  events are indicated in the chart by lines or crosses;
• Database window - events are available for some of the demo files;
• Quick Renderer - select an event to jump straight to it;
• Strobe image editor - events specify which frames to use;
• Wizard window - on an apas3d element on the Quick Events tab.
